How to Use Objects

[munna]

I think it should be something like

void MyDialog::showDialogSuchen()
{
   DialogSuchen dialogsuchen(this);
   connect(&dialogsuchen,SIGNAL(sendString(QString)), this, SLOT(onSendString(QString)));
   dialogsuchen.exec();
}

void MyDialog::showDialogSuchen()
{
   DialogSuchen dialogsuchen(this);
   connect(&dialogsuchen,SIGNAL(sendString(QString)), this, SLOT(onSendString(QString)));
   dialogsuchen.exec();
}

To copy to clipboard, switch view to plain text mode 

void DialogSuchen::onSendString()
{
    emit sendString(ui.lineEdit->text());
}

void DialogSuchen::onSendString()
{
    emit sendString(ui.lineEdit->text());
}
